Abstract

A networked projection system having a client computer operatively connected to a projection computer including a content controller that captures and processes presentation media located on the client computer, and a network projection controller located on the projection computer that provides an interface between the content controller and a projector operatively connected to the projection computer.

Claims

1. A networked projection system having a client computer operatively connected to a projection computer, comprising:

a content controller that captures and processes presentation media located on the client computer; and

a network projection controller located on the projection computer that provides an interface between the content controller and a projector operatively connected to the projection computer.

2. The system of claim 1, further comprising:

a user interface located on the client computer for accessing and controlling the networked projection system.

3. The system of claim 1, further comprising:

a presentation application located on the client computer for executing and displaying presentation media on a display device.

4. The system of claim 1, further comprising:

a media server located on the client computer that processes and packages presentation media to send to the network projection controller.

5. The system of claim 4, wherein the media server is an audio server.

6. The system of claim 4, wherein the media server is a video server.

7. The system of claim 1, wherein the network projection controller is located on a microprocessor on the projector.

8. The system of claim 1, wherein the network projection controller comprises:

a projection server serving up Hypertext Mark-up Language documents and associated files requested by the client computer;

a projection controller operatively connected to the projection server controlling projector functionality; and

a content viewer operatively connected to the projection server for reconstructing captured presentation media.

9. The system of claim 8, further comprising:

a media client configured to reconstruct specific portions of the presentation media.

10. The system of claim 9, wherein the media client is an audio client.

11. The system of claim 9, wherein the media client is a video client.

12. A networked projection system having a client computer operatively connected to a projection computer, comprising:

a content controller that captures and processes presentation media located on the client computer;

a network projection controller located on the projection computer that provides an interface between the content controller and a projector operatively connected to the projection computer;

a user interface located on the client computer for accessing and controlling the networked projection system;

a presentation application located on the client computer for executing and displaying presentation media on a display device; and

a media server located on the client computer that processes and packages presentation media to send to the network projection controller.

13. A method for using a networked projection system, comprising:

connecting to a projection server from a client computer;

accessing the projection server from the client computer;

determining if a content controller is located on the client computer by the projection server;

loading the content controller and media servers if the content controller is not located on the client computer;

initializing the content controller on the client computer by the projection server;

executing a presentation using a presentation application on the client computer;

capturing presentation media by the content controller;

processing presentation media on the client computer by the content controller;

forwarding processed presentation media from the client computer to the projection server;

reconstructing presentation media by a media viewer operatively connected to the projection server; and

outputting reconstructed presentation media to a projector.

14. The method of claim 13, wherein the client computer uses Transport Connection Protocol/Internet Protocol to connect to the projection server.

15. The method of claim 13, wherein the content controller and the media server are loaded using a plugin technology.

16. The method of claim 13, wherein the content controller executed as a background process on the client computer.

17. The method of claim 13, wherein the presentation application executed as a foreground process on the client computer.

18. The method of claim 13, wherein the presentation media captured by the content controller is processed using a media server.

19. The method of claim 18, wherein the media server is an audio server.

20. The method of claim 18, wherein the media server is a video server.

21. The method of claim 13, wherein the media viewer is a content viewer.

22. The method of claim 13, wherein the media viewer is a media client.

23. The method of claim 22, wherein the media client is an audio client.

24. The method of claim 22, wherein the media client is a video client.

25. The method of claim 13, wherein presentation media is output to the projector system via an Infrared connection.

26. The method of claim 13, wherein presentation media is output to the projector system via a direct serial connection.

27. An apparatus for using a networked projection system, comprising:

means for connecting to a projection server from a client computer;

means for accessing the projection server from the client computer;

means for determining if a content controller is located on the client computer by the projection server;

means for loading the content controller and media servers if the content controller is not located on the client computer;

means for initializing the content controller on the client computer by the projection server;

means for executing a presentation using a presentation application on the client computer;

means for capturing presentation media by the content controller;

means for processing presentation media on the client computer by the content controller;

means for forwarding processed presentation media from the client computer to the projection server;

means for reconstructing presentation media by a media viewer operatively connected to the projection server; and

means for outputting reconstructed presentation media to a projector.
